The issue is related to the SUNRPC module in the Linux kernel, specifically with the function gss free in token pages(). The in token->pages[] array is not NULL terminated, resulting in a potential wild-memory-access issue. This can lead to a denial of service. The vulnerability is associated with insufficient memory allocation for an operation in the gss read proxy verf() function.

The issue allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging improper access to a certain error field in the ext4 journal stop function.
